Meltblown fabric production line meltblown cloth mask manufacturer direct sales

Working principle:

The plastic extruder has been developed for more than two hundred years since its birth. Now the technology of single screw extruder is very mature.

In general, the single-screw extruder can be divided into three working areas according to the screw: conveying section, compression section and metering section.

The last thread of the material opening is called the conveying section. At this stage, the material is required not to be plasticized, and it is mainly used for conveying the material.

A cooling device is also installed on some large-diameter extruders to prevent the material from plasticizing and to avoid affecting the material conveying speed due to the melting of the material.

When the material passes through the conveying section, it enters the compression section at this time. At this stage, the volume between the screw and the barrel becomes smaller. At the same time, the temperature reaches the plasticizing temperature, and the material will be compressed.

When the material completes the plasticizing operation, it will enter the metering section. Quantitatively conveying melt material to feed the head for production needs.
